What are the best practices for configuring port-channels on an Aruba controller?

We can bundle two or more ports in an aruba controller to form a port channel. What are the best practices for configuring the same?

A:

1. Use LACP for port channel rather than a static port channel. LACP will negotiate the configuration with the uplink device and will not use a port if there is any misconfiguration. We can see the port channel type by the command:

2. A port channel is untrusted by default. This will force all the traffic to enter the user table. This might result in APs doing down / coming up as inactive / dirty flag. Thus we must trust a port channel manually:

(Master) #configure t
Enter Configuration commands, one per line. End with CNTL/Z

3. If possible, configure EVEN number of member of port channels. This will allow even hash distribution resulting in more equal bandwidth utilization across the links.

4. a member port inherits the configuration of the port channel. Thus the port level configuration (like spanning tree, trunk mode native vlan etc.) should only be configured on the port channel interface and not on the member ports:
